摘要
Despite the explosion of interest in topological materials over the last decades,their applications remain limited due to challenges in growth and incorporation with today’s microelectronics.As a potential bridge to close this gap,we investigate the group-IV alloy Ge_(1–x)Pb_(x),in the Ge-rich condition using density functional theory and show that relatively low concentrations of Pb(~9.4%)can lead to a topological phase transition.
